Filings add to questions on Warren’s ethnic claims

US Senate candidate Elizabeth Warren has said she was unaware that Harvard Law School had been promoting her purported Native American heritage until she read about it in a newspaper several weeks ago.

But for at least six straight years during Warren’s tenure, Harvard University reported in federally mandated diversity statistics that it had a Native American woman in its senior ranks at the law school. According to both Harvard officials and federal guidelines, those statistics are almost always based on the way employees describe themselves.
